* introduce defaultDimension() and dimension() in preparation of Dimension class cleanup.

- ucs4_to_qchar(): add a FIXME and an assertion
* GuiFontMetrics: replace the table based cache with two QHash based cache. With this change, the speed overhead is not negligible (exact same score with the UserGuide test) and the required additional memory is minimal (maybe one or two megabytes).

- add constants instead of hard-coded values.
- add assertions and comments for out of range values.

The only drawback is that it requires about 20Mo extra-memory when loading the UserGuide. If it turns out to be too much, we can switch to a QHash based solution instead of a table.
* dimension.[Ch]:
- Dimension(LyXFont const, char_typec): new ctor
- set(LyXFont const & font, char_type c): new method.
* frontends/FontMetrics.h:
- width(char_type): is now a pure virtual method.
* GuiFontMetrics:
- CharMetrics: new structure;
- the metrics cache now also cache ascent and descent. This is especially useful for mathed.
* MathSupport.[Ch]:
- mathed_char_dim(): deleted. We now use Dimension::set() directly instead.
* rowpainter.C: fixe empty space.

* QLPainter::paintText(): use GuiFontMetrics::metrics(QString) to avoid an ucs4 to QString conversion.

- Various micro-optimisations
- Revert Abdel's repaint instead of update for QPainter
- Get rid of unused methods in GuiWorkArea

* lyx_main.h: define "extern bool lyx::use_gui" here.
* NoGuiFontMetrics.h: new class for command-line LyX
* NoGuiFontLoader.h: new class for command-line LyX
* Application.C:
- theFontMetrics(): returns the above dummy FontMetrics when use_gui is false.
- theFontLoader(): returns the above dummy FontLoader when use_gui is false.

Only qt4 is guaranted to compile and work. I did not remove gtk and qt3 lyx_gui.C because they might be needed for reference to complete the header declarations in "GuiApplication.C".
- lyx_gui::use_gui transfered to lyx::use_gui in lyx_main.C
- all remaining lyx_gui functions transfered to Application and corresponding GuiApplication implementations.

- ucs4_to_qchar() and qchar_to_ucs4() have been inlined.
- ucs4_to_qstring(): pass a QString to avoid a copy.

Basically, I replaced all methods in the font_metrics namespace by a proper virtual interface FontMetrics. The FontLoader is _the_ container for FontMetrics.
This patch should also bring some optimizations in a number of place in the code. This is because we do not need any more to search for the LyXFont at each font_metrics call. In effect, the speed advantage is not as sensible and this is a bit deceiving considering that this was my primary motivation behind the patch. But I like the patch anyway as it cleans up the relation and interfacing between fonts, metrics and frontends.
* frontends/FontMetrics.h: new virtual interface. Renamed from font_metrics.h
* qt4/GuiFontMetrics: corresponding qt4 implememtation. Renamed from qfont_metrics.C. The smallCaps particular case treatment has been transfered here as well as the width cache for MacOSX and Windows.
* qt4/QLPainter.C: the smallCapsText has been reworked to return the width of the drawn text.C
all other files: replace font_metric helper function call with corresponding FontMetrics method calls.
